The turbo-freq enable with auto mode, prints result for the last possible CPU, which is not correct when either CPU is not present or user wants command to be limited to a single die/package.

Mausezahn does not recognize "own" as a keyword on source IP address. As a result, the MC stream is not running at all, and therefore no UC degradation can be observed even in principle. Fix the invocation, and tighten the test: due to the minimum shaper configured at the MC TCs, we always expect about 20% degradation. Fail the test if it is lower.

2020-01-11bpftool: Fix printing incorrect pointer in btf_dump_ptrMartin KaFai Lau1-1/+1
For plain text output, it incorrectly prints the pointer value "void *data". The "void *data" is actually pointing to memory that contains a bpf-map's value. The intention is to print the content of the bpf-map's value instead of printing the pointer pointing to the bpf-map's value. In this case, a member of the bpf-map's value is a pointer type. Thus, it should print the "*(void **)data".

2019-12-23rseq/selftests: Clarify rseq_prepare_unload() helper requirementsMathieu Desnoyers1-5/+7
The rseq.h UAPI now documents that the rseq_cs field must be cleared before reclaiming memory that contains the targeted struct rseq_cs, but also that the rseq_cs field must be cleared before reclaiming memory of the code pointed to by the rseq_cs start_ip and post_commit_offset fields. While we can expect that use of dlclose(3) will typically unmap both struct rseq_cs and its associated code at once, nothing would theoretically prevent a JIT from reclaiming the code without reclaiming the struct rseq_cs, which would erroneously allow the kernel to consider new code which is not a rseq critical section as a rseq critical section following a code reclaim.

2019-12-20perf map: Set kmap->kmaps backpointer for main kernel map chunksArnaldo Carvalho de Melo1-0/+3
When a map is create to represent the main kernel area (vmlinux) with map__new2() we allocate an extra area to store a pointer to the 'struct maps' for the kernel maps, so that we can access that struct when loading ELF files or kallsyms, as we will need to split it in multiple maps, one per kernel module or ELF section (such as ".init.text"). So when map->dso->kernel is non-zero, it is expected that map__kmap(map)->kmaps to be set to the tree of kernel maps (modules, chunks of the main kernel, bpf progs put in place via PERF_RECORD_KSYMBOL, the main kernel). This was not the case when we were splitting the main kernel into chunks for its ELF sections, which ended up making 'perf report --children' processing a perf.data file with callchains to trip on __map__is_kernel(), when we press ENTER to see the popup menu for main histogram entries that starts at a symbol in the ".init.text" ELF section, e.g.: - 8.83% 0.00% swapper [kernel.vmlinux].init.text [k] start_kernel start_kernel cpu_startup_entry do_idle cpuidle_enter cpuidle_enter_state intel_idle Fix it.

2019-12-20perf report: Fix incorrectly added dimensions as switch perf data fileJin Yao1-1/+4
We observed an issue that was some extra columns displayed after switching perf data file in browser. The steps to reproduce: 1. perf record -a -e cycles,instructions -- sleep 3 2. perf report --group 3. In browser, we use hotkey 's' to switch to another perf.data 4. Now in browser, the extra columns 'Self' and 'Children' are displayed. The issue is setup_sorting() executed again after repeat path, so dimensions are added again. This patch checks the last key returned from __cmd_report(). If it's K_SWITCH_INPUT_DATA, skips the setup_sorting().
